Discussion

Plants of Digitalis grandiflora are occasionally found in cultivation and sometimes escape in the northeastern part of the flora area.

Although the names Digitalis grandiflora and D. orientalis were published at the same time, D. grandiflora has long been the preferred name for this species and has been in general use since it was published. The name D. orientalis Miller was long confused with the later homonym D. orientalis Lamarck, a synonym of D. lanata.
